MACHINE FOR LAYINGCHANNEL-FLAPS OF BOOT OR SHOE SOLES.

SPECIFICATION forming' part Of Letters Patent No. 426,374, dated April 22, 1890.

Application iiled November 14, 1889. Serial No. 330,255. (No Inodeldv Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Devices for Laying Channel-Flaps of Boot- Or Shoe Soles, of which the following is a specification.

This invention has for its Object to provide simple and eiiicient means for pressing down the chanuel-iiaps of 1nachine-sewed boot Or shoe soles after the stitching Operationv has been performed; and it consists in a wheel or disk andaseries of spring-supported studs iitted tO slide in radial sockets in said wheel, their Outer ends being rounded and presenting a series Of independent convex rubbingsurfaces, which are caused by the supporting springs to bear with a yieldin gpressureagainst a sole presented to the periphery of the Wheel, as I will new proceed to describe and claim.

Of the accompanying drawings, forming a part of this specicatiOn,Figure I represents a side elevation of my improved nap-laying wheel, showing its supporting-shaft and the bearings therefor. Fig. 2 represents an end elevation Of the same. Fig. 3 represents a section on line 3 3, Fig. 2.

The same letters Of reference indicate the same parts in all the figures.

In the drawings, a represents the wheel, which is preferably composed Aof the web Or body portion 2 and the circular rim or peripheral portion l, offset from the web, the wheel being affixed to a shaft b, which is journaled in bearings c c and rotated by any suitable power.

In the rim 3 are drilled a series of radial sockets d, in which are fitted aseries Of studs e, said studs being metal cylinders adapted to slide freely in the sockets d and provided with convex Outer ends.

Springs f are interposed between the inner ends Of the studs and the bottoms of the sockets d, said springs pressing' the studs outwardly. The studs are provided with Shanks e', which pass through oriiices in the bottoms of the sockets d and are provided with heads or enlargements e2, bearing-against the inner surface 'of the rim 3, said heads preventing the studs from being forced out from their sockets by the springs f. Any other suitable means may be employed, however, tO prevent the removal of the studs,myinvention not being limited in this particular to the devices here shown.

It will be seen that the outer ends of the studs e constitute a series of convex metallic rubbing-surfaces located in close proximity to each other, so that collectively they will act- On a surface Of the same width as the distance between the Outer edges of the outer rows of studs. The studs, being independent of each other, are enabled tO yield independently, so that they can conform to theinequalities and curves of the sole-bottom on which they act.

The convex form of the outer ends of the studs enables them to rub the flap down smoothly without scratching or injuring the same.

I claim- The improved flap-laying device, composed of the Wheel having radial sockets, studs tted to slide independently in said sockets, springs within the sockets supporting the studs, and means for preventing the removal Of the studs from the sockets, the studs having convex Outer ends constitutingindependent rubbing-surfaces, as set forth.

In testimony whereof I have signed my name to this specification, in the presence of two subscribing witnesses, this 4th day of November, A. D. 1889.

WILLIAM GORDON. Witnesses:
